The invention consists in combiningadjustable diagonal bars with a gatefor the purpose of supporting its front end, and thus prevent ing ortaking up sag, or adapting it to pass over an inclined or unevensurface, as hereinafter described.

A is the front or latch-end bar, and B is the rear or hinge-end bar, ofthe gate. In the inner sides of the bars A B are formed shallowmortises, to receive the ends of the longitudinal bars 0, as shown indotted lines in Fig. l. D are inclined brace-bars, placed upon theopposite sides of the gates, and crossing each other and thelongitudinal bars (J di agonally, as shown in Fig. 1. To the lower endsof the brace-bars D are bolted metallic straps or plates E, the lowerends of which overlap the sides of the end bars A B, and are secured tosaid bars A B each with a single bolt. 111 the case of the rear end barB the lower hinge F serves as a bolt for securing the lower end of thestrap E. To the upper end of the brace D are bolted straps G, the upperends of which overlap the sides of the upper ends of the end bars A B,and have hooks formed upon the said upper ends, which enter holes in thesaid end bars A B. Several holes are formed in the upper ends of the endbars A B, to receive the books of the straps- G. The middle parts of thebrace-bars D have holes formed through them to receive a bolt, H, bywhich they are secured to each other, clamping the longitudinal bars 0between them, and preventing the hooks of the strap G from being drawnout of their holes without first loosening or detaching the said bolt H.As many holes are formed in the bracebars D as there are holes in theupper parts of the end bars A B, so that the bolt H may be adjusted.

The above-described construction and arrangement of parts enable thefront end bar A to be raised or adjusted higher, as occasion requiresforexample, when the gate has sagged, or when the inclination of the groundtion, renders it necessary. A

The adjustment is made by changing the hooks G to the next hole above.The end bars A B remain parallel, whatever be the adjustment of thefront bar A.

The second longitudinal bar a from the top passes through a mortise inthe front end bar A, and projects, to serve as a latch for fasteningthegate. The latch c is held forward, and at the same time allowed toyield in opening and closing the gate, by a coil-spring, I, inserted ina mortise in the rear end bar B, behind the rear end of the saidlatch-bar c. This construction enables the gate to latch itself as it isswung shut. The latch c is pushed back to unfasten the gate by a lever,J, pivoted to it and to the top longitudinal bar 0, as shown in Fig. 1.

It will be observed that no bolts, nails, pins, or other fastenings areused for holding the various parts of the gate together except thoseconnected with the brace-bars D.

This same construction may be used for doors, if desired.

In the case of gates, the lower hinge F is applied to the side of therear end bar B, and the upper hinge K is applied to the rear side ofsaid end bar, as shown in Figs. 1 and 2, so that the forward end of thegate may rise as the gates are opened, and so that the gates may swingshut automatically when released.

Having thus described my invention, what I claim as new, and desireto'secure by Letters Patent, is-

The combination, with horizontal bars O and vertical end bars A B,having holes at the top, as specified, of the diagonal crossed bars D,their central connecting-bolt H, the straps E, and hooks G, as shown anddescribed, whereby said hooks 'may be adjusted to effect the adjustmentof the front or latch end of the gate.
